Abstract : This paper presents an experimental-numerical study based on simple tensile test of a high strength metallic sheet, including the diffuse necking stage, up to the large plastic strain and damage localization. A micromorphic approach including nonlocal damage can overcome the mesh dependency problem. The numerical implementation into ABAQUS/Explicit is made for 2D quadrangular elements thanks to the VUEL user’s subroutine. Promising results are obtained which qualitatively are compatible with the experiments.
